WASHBOILER.

Application filed March 25, 1927, Serial No. 178,231, and. in GermanyJuly 2;;l 192g' The present invention relates to a new and improvedapparatus to treat solid material with liquids, to treat textile goodswith water for washing and rinsingpurposes.

The invention relates more particularly to an apparatus of the saidclass in which a pulsating movement is imparted to liquids the latterbeing driven periodically in alternating directions through a chambercontaining the goods to be treated.

The main objectof the invention consists in the provision of the meansto impart the pulsating movement to liquids within the working chamberitself and in the construction of said means in such a manner that thepulsating movement occurs most regularly and at short intervals of timeacross the goods to be treated.

A further object consists in the provision oi" means to ensure theautomatic action of the apparatus the automatic reversal of thedirection of flow of liquids through the working chamber and through thegoods contained therein.

A still further object of Athe invention is to provide means to create aflow of liquids independent of the said pulsating movement across thesaid chamber the .liquids having to pass through the goods in saidchamber.

lVith these and other objects in view the invention resides in thefunction, combination and arrangement of parts which will be bestunderstood and appreciated from the following description of a preferredembodiment thereof.

In the accompanying drawings the preferred construction of the apparatusis shown in a diagrammatical manner in a sectional elevation in Figure 1and Figure 2 is a. transverse sectional view taken on lines 2-2 ofFigure 1.

The apparatus shown comprises a closed bottomed cylindrical vessel 1adapted to contain liquid. The vessel 1 is placed above a grate in asuitable stand which itself forms no part of the invention and which maybe made in any convenient manner. The vessel 1 is closed by a lid. Onthe bottom of the vessel 1 rests a dome 2. The dome 2 is of sheet metal,and is provided at its outer circumference with a downwardly projectingflange or rim in which holes or slots l are arranged. The dome 2 isfurther provided with a central aperture 3. Above the dome 2 a bell 12is submerged in the liquid and within said bell 12 a cage or container13 is arranged, adapted to receive the clothes to be treated. The wallsof the cage 13 are of sheet metal and are provided with holes 13a, orthey may consist of other perforated construction. The diameter of thebell 12 is rather less than the diameter of the vessel 1, an annularspace 8 is left between said parts `1 and 12 surrounding the bell 12 andallowing the passage of liquids. The cage 13 has a central cylinder 5,which is perforated; 7 is a `tube leading from below the top 17 of theinterior of the bell y12 to the space 15 above saidk bell. The lower endof the tube 7 dips into and is scaled by water contained in auupwardlydirected cup 6. rl`he said cup (i which is closed at itsI lower end isfastened at .its upper end to a circular disk 9, being provided with anopening 9a communicating with the interior of the cup 6 and having anupwardly directed rim at its outer edge. ln said rim holes or slots 10are arranged to communicate with the interior of the bell 12.

The cup G is surrounded by heat insulating material 6 such as cork etc.The diameters of tube 7 and of cup 6 are such that a passage 1G isformed through which the water passes yfreely from the space 15 to theinterior of the working space or chamber 18. The outer edge of the top17 of the bell 12 is slightly raised by an annular collar 19 above thecentre where the tube 7 is connected in such a manner that suiiicientwater is retained' to till the water seal as and for the purooscdescribed hereinafter'.

According to the embodiment of my invention illustrated in the drawing,the vessel 1 provided with a flange 20, which .is disposed adjacent thelower end thereof, and vhich rests upon a water jacket 21 in the form ofan annular chamber' projecting upwardly from a grate supporting platform22. The space, within the inner annular wall of the water `iacket 21,provides the heating chamber for the vessel 1 and communication with thespace is made through adoor 23. A grate 2li is supported centrally ofthe platform 22 and a depending pit 25 is disposed beneath the grate. Apan 26 is slidable in the pit to form a collection receptacle directlyunder the grate.

On heat being applied to the bottom of the vessel 1 the water thereinwill flow upwards through the aperture 3, water being drawn in throughthe slots l. The water passes through the cage 12'?) and through thegoods placed therein, an eil'ective' Lminterrupted circulation ol" thewater occurs. Further heat being` applied the Water in the vessel lWithin the Working` chamber' will eventually boil and the steamtherefrom Will accumulate beneath the bell l2. lIlle steam underpressure will gradually depress the level of the Water in the bell 12and in the cage 13. The Water ejected 'from the bell i'lows through ftheannular space S and through the tube 'T into the space l5 above the belll2. At the same time as the level of the Water is depressed Within thebell l2 the level ol the Water in the cup iis also depressed by theincreasing` steam pressure in the Working chamber lS. As as the lowerend ot the tribe '7 is uncovered steam vvill blow out through the tube 7ejecting` the Water therein. Steam passes into the space l5, thus theaccumulated pressure in the bell l2 will be relieved and the level olthe Water in the space l5 being no longer sustained Will fall throughthe annular passage 8. The Water periodically rises and falls and a.regular pulsation .ot a great amplitude is obtained by automaticallyvierking means. Besides this pulsation a regular circulation ol theWater is effected by the dome 2, the Water flowing' through the`openings l into the dome 2 rises after being' heated through theaperture 3. Illhile the steam `generated accumulates in the bell 'the'Water passes through the perforated -Walls olf the cage 18 on to theclothes The upper extension 9 ot the cup 6 prevents the rising' Waterwhich contains steam bubbles troni passingl into the tube 7. It suchhighlyY heated Water would enter the said tube 7, steam would escape tooearly and the periodical function of the apparatus would not beattained. The insulation on the cup 6 prevents the Water in the seal 6,from being' heated to such an extent that the automatic function of theapparatus would be interfered with. To make sure that the seal G, 7 isbeing' supplied With Water the outer edge. of the Wall 17 of the bell israised by an annular collar 19 to prevent some or the Water in the spacel5 from flowing-2 down through the annular space 8.

A valve 27 is provided in the top l? of the bell 12 so as to providemanually operated means to establish communication between the chambersand 15. The valve 27 is spring supported and in the event ot' an excessof steam in chamber l5, the pressure will be exerted against the valvewhich will open to permit escape into the space 10.

Other modes ,of applying the principle ol' my invention may be employedinstead oil? the one explained and I do not Wish to limit my inventionto the particular means as shown and described except as limited by theclaims.

What I Wish to secure by United States Letters Patent is l. ln anapparatus lor treating@y solid with liquids to which a pulsatingr cage,a tube projecting` into said cylinder fixed to the lop ot the bell, andinsulated means surrounding' the said tube to form a liquid sealclosing' the loiver end of the tube.
